TCP Client / Server Tool

VG-Software

About this app

• Two-in-One (Client & Server Mode)
Swiftly switch between TCP client and TCP server. Exclusively controlled at all times to prevent port conflicts.

• TCP Client
Connect to any target IP address or hostname via configurable ports (1–65535) with automatic status feedback, loading indicator, and automatic saving of the last IP/port configuration.

• TCP Server
Start a TCP server on any port (also saved for the next session). Your local Wi-Fi/LAN IP address is displayed directly to facilitate connection for other devices. A counter for connected clients is included.

• Chat-like Log View
Incoming (📥) and sent (📤) messages, as well as system messages (⚙️), are displayed in clear, color-coded tiles with timestamps and IP information.

• Switchable HEX and TEXT View
Switch between plain text (UTF-8) and raw data display in hexadecimal format (e.g., 48 65 6C 6C 6F) in real time with a single tap. Hex view can also be set as the default in the settings.

• Flexible Send Options & Options Tab
Manage send options, line endings (CRLF, LF, None), and STX/ETX framing centrally and clearly in a dedicated Options tab.

• STX (0x02) & ETX (0x03) Framing Support
Enable automatic STX/ETX framing. Start and end characters are automatically added during transmission and hidden in the text format for optimal readability.


• • Full Data Export

Export your message logs in TXT, CSV, or JSON format. Save files directly to your device, share them via email/messenger, or copy data to the clipboard.

• Bilingual (German & English)
Automatic system language detection with the option to manually change the app language at any time in the settings.
